This commit introduces a new package `pkg/fips` that bundles functionality to handle and configure cryptographic protocols in case of FIPS 140. If it is compiled with `--tags=fips` it assumes that a FIPS 140-2 cryptographic module is used to implement all FIPS compliant cryptographic primitives - like AES, SHA-256, ... In "FIPS mode" it excludes all non-FIPS compliant cryptographic primitives from the protocol parameters.

// Package fips provides functionality to configure cryptographic

// implementations compliant with FIPS 140.
|

|
|
// FIPS 140 [1] is a US standard for data processing that specifies
|
|
// requirements for cryptographic modules. Software that is "FIPS 140
|
|
// compliant" must use approved cryptographic primitives only and that
|
|
// are implemented by a FIPS 140 certified cryptographic module.
|
|
//
|
|
// So, FIPS 140 requires that a certified implementation of e.g. AES
|
|
// is used to implement more high-level cryptographic protocols.
|
|
// It does not require any specific security criteria for those
|
|
// high-level protocols. FIPS 140 focuses only on the implementation
|
|
// and usage of the most low-level cryptographic building blocks.
